To provide a power supply system that allows the current maximum power generation capability to be easily recognized, this power supply system includes a plurality of fuel cells for generating power and supplying the power to loads; a performance storage section for storing a maximum power value indicating a maximum value of a power generation ability of each fuel cell; a test device for sequentially performing maximum power generation testing on at least one of the fuel cells at a predetermined time interval; an update section for updating the maximum power value of each fuel cell, the maximum power value being stored on the performance storage section, according to a result of the performance test; a power-generation-amount detection section for detecting the total of amounts of power generated and supplied by the fuel cells to the loads; and a surplus-power determination section for determining surplus power, which can be excessively generated by the power supply system, at the predetermined time interval based on a difference between the total of the maximum power values stored on the performance storage section and the total of amounts of the power generated.
